One of the things I really liked in terms of mechanics was being able to use the terrain to my advantage. Being able to ambush enemies from high ground, flanking mechanics, the archer height bonus and the destructible cover in dragon fights all gave the combat a more natural feel for me, and opened up a much wider range of tactical options.
With that said I think that there is a lot more that could be done to expand upon these ideas.
- Ambush bonuses from heavy ground cover
- Breaking line of sight to reduce or even drop aggro
- If we're feeling really ambitious, a way to set up environmental traps (rockslides, pitfalls etc.)
Most importantly, if mechanics like these are implemented, I would like to see using them in some way become almost a necessity. Groups large enough that you have to split them up or cripple them before engaging for instance.
Really, almost anything that gives me more options in terms of how to approach combat would be welcome.
As for story and plot, the reason I have been happily playing Bioware games for the past... what, 15 years?... is very simple. The characters. Period. End of the line.
All the game mechanics, the graphics and even the actual plot are secondary for me. To that end, I think what I would like to see is :
- More and more substantive "minor" dialog. Not every talk needs to be earthshattering or super-informative. Being able to have what feels like a real conversation inbetween plot points does wonders for immersion, and these often seem to be the most memorable moments for me. Learning about Cassandra's choice of reading material is the perfect example of this. I loved that scene to pieces, and perhaps more importantly it forever changed the way I view her. Scenes like that build on the character, while all her information about the Seekers etc. built on the world.
- More contextual conversations. Not just a line or two of banter, more like Bull's reaction to your first dragon kill. Similar to reasons above.
Okay, this one I'm a little unsure of, but I'll try to explain it as best I can.
One thing that strikes me about many Bioware characters is how confident they are in themselves their views. I don't mean that they are unyielding, being able to influence your companions to see new points of view is kind of a longstanding tradition. I mean that most people I've met have in some form had conflicting views on nearly everything. That kind of tangled indecision and contradiction seems far more natural to me than the straight line of confidence found in many games.
